We include EV’s
because about half of
our easily-fixed
spiritual energy is
spent driving to church

At AFM we currently burn Propane for heat (not shown here)
Tired of
hearing:
When is the Payback ???
When is the Breakeven ???
Paying for at-home Garbage Pickup is from Day ONE !
Tired of
hearing:
When is the Payback ???
When is the Breakeven ???
Paying for Sewage Plants –
is from Day ONE !
Tired of
hearing:
When is the Payback ???
When is the Breakeven ???
Paying for Solar Power - is from Day ONE !
Because that’s when we Stop Beating Mother
Nature and stealing from our kids future.
Big
Picture!
1 House, 1 Year consumes 4 Tons
of coal worth of
electricity
Yes, we have 100 years of coal, but there won’t be anything left of WV!
OUR PRESENT LIFESTYLE
IS NOT SUSTAINABLE!
Are we
part of
the
problem?
Or part
of the
Solution?
Solar panels
eliminate carbon
just like trees!
SOLAR Panels
are equal to trees
for
Carbon elimination
Each Panel = 8 Trees.
Our system = 312 trees!
= (3 acres of trees)
Buy trees
or solar!
When is the Breakeven ???
CARBON
Carbon Benefit - is from Day ONE !
If you compare based on carbon impact
Lighting: Save 4 to 1 Energy!
(breakeven in 5 days!)
Cost 50 cents.
$2
Save $50 over the
life of the bulb!
House with 50
bulbs saves $2500
Only 1 in 4 households do it!
35,000
Solar Power is here. 50% energy savings!
2012
Solar Cost!
Equaled Utility in 2010
Half the Utility in 2013
2009
2013
It’s a Whole New World!
Grid-Tie
• Cost effective in EVERY state since 2009!
Grid-tie Revolutionized Solar
• No Batteries!
Grid-Tie
Every Watt Produced is valued at full Retail Rates!
Angles - less important
with Grid-Tie
Amazing, even due East, you still get 85% effectiveness!
Angles - less important,
More Roof is!
Amazing! Increase power by 60% to 100% on other side!
Government Incentives!
• Federal gives 30% tax credit. No limit
• State of Maryland Grant

In 2010 for our 8kW system was $7000
In 2011 was $5000
In 2013 was $1000
In 2014 is ??? (argh!)
• AA County Real Estate Tax credit
– $2500
• Total Gov’t Tax Credits return ~ 40% of investment!

• Total Gov’t Tax Credits return ~ 40% of investment!
But not for tax-exempt Churches!
Work-Around for Churches!
• Workaround = Solar Lease or PPA
• Example Lease Program
– 0 money down save 15% over 20 years &
– 100% down save 50% over 20 years on Today’s rates! &
– But rates will probably go up X 2 over same time
– So result is paying about 1/4th for electricity?
• Faith Groups are in it for the long term…
Just do it…
Grid Solar Power = Emergency Power
• COMPLETELY DIVORCE any thoughts of “emergency
power” from Economical power.
• Solar power (grid-tie) is for ECONOMICAL POWER!
• Emergency power has completely different optimal
solutions. (Short term and Armageddon)

$10,000

Solar Power *is* Economical
You have $24,000 in the bank.
Lets say your electric bill is $200/mo. Or $2400/yr or $24,000 over 10 yrs
Keep $24,000 in a bank at 1%. Continue to pay $200/m for Electricity
* After 10 years, you have paid $24,000 with NOTHING to show for it
* And every year you have uncertainty in ever rising prices
• And you will keep paying > $24,000 or more every ten years
• And your Savings in the bank has only grown by $2400
Buy a $40,000 solar system now, ( With incentives, Pay only $24,000)
* Have maintenance free electricity for LIFE
* It is generating $2400/year return on investment (10%) for LIFE
* You OWN this $40,000 energy system and all it’s equity for life
* After 25 years it is still producing 80% of today’s power! (and will continue)
Don’t wait, Solar is the best investment there is!

8% - 10%
Considering your future of death, taxes and utilities,
you can do something about your utilities!
Utility
Solar
Design Solar to about
90% of need
Electric Need
The more we invest in renewable energy,
The more we become Energy conscious
The less we waste
The more efficient and sustainable we become!
Appliances also are getting more efficient.
Generally Solar converts begin to save energy
and reduce their remaining Utility Bill to ZERO!
Solar
Solar Zero-down LEASE Example
Zero Down Lease
Usually design for
90% of usage
(assume savings and
Improving appliances)
For $0 down and monthly lease, can beat utility by 15%*
&
*assuming utility rates rise an average 2.9% annually
Annapolis Friends Meeting Pre-Pay Example
(BGE=14¢)

SREC’s =
$250/mWhr

Annapolis Friends Meeting 9 kW Array
System Components
Inverter
Circuit Breaker
Sturdy (don’t do this at home!)
Roof Issues:
* Is 20 yrs old, plenty of life (but not another 20)
* Is shaded
We chose a ground mount system
Annapolis Friends Meeting 9 kW Array
Orientation chosen to maximize Solar & minimize neighbor view
Annapolis Friends Meeting 9 kW Array
Typically, Arrays follow
the lay-of-the-land.
But with our steep
slope, we chose to keep
horizontal & adjust
edge, but had to pay an
extra $1000 for unique
engineering
Annapolis Friends Meeting 9 kW Array
Choosing Tilt Angle
Tilt angle chosen was 25 deg instead of 35 deg to
reduce visibilty ( less than 1% less than ideal)
Notice also that orienting to SE or SW would only
lose less than 3% from ideal.
50% Energy Spent Driving to
Church
50% of Church’s energy/emissions due to driving!
With the Solar array, EV driving is 100% renewable

Plug-in at work (double range, quadruple area)
Charge at home only = 16 mi range (chevy Volt)
Charge L1 at work/home = 64 mi range
from 2200 gal/year down to 100 gal/year
And we help Environment
And save money!
Solar Water Heating – WAS Best Application for solar
from 1950 - 2005
Best energy capture per sqft…
back in 1950-2005
Solar PV is now EQUAL to Thermal hot water…
Heatpump water heating is a game-changer !
!
Solar PV is actually BETTER than Thermal hot water…
!
If 100% hot water not used EVERYDAY…
then Excess solar everyday is lost
With PV, 100% of solar energy gives
full retail value,
Independent of how you use it!
So, Lets do the right thing…
Move forward with clean Energy

At AFM we currently burn Propane for heat
But we should add Heating Energy (Propane)
Solar Power for Electricity
Electric Vehicle Support
Our biggest fossil burning
is for Propane heating!

When we convert to a
G.S. heatpump we will
need to DOUBLE our
solar, but we CAN! and
we will be carbon free!
At AFM we currently burn Propane for heat
Church Heating Costs
Propane…
Actually our biggest
Energy cost is our
Propane heating.
Switching to Ground
Source Heatpump
will be our next major
Environmental
Project
Switching from
Propane to
Ground Source
Heatpump
Our heating costs will go
down 60% AND being
electric, we can replace
that with solar for
additional savings!
